Medi0gre's Grindhouse

My room became a concept in 2012 after i googled home theater looking for ideas on how to tweak my 5.1 setup... Should i buy a Klipsh sub or maybe a Velodyne sub? etc, etc.
Then i ran into you guys and I ate the red pill.

Room Dimensions 20' x 10' 9" x 7' 6"

Sound proofing design goals were to keep outside noise out of theater, Single layer 5/8x walls and ceiling. The ceiling did get whisper clips and channel.
Hvac was isolated with mufflers and hush box.
20 amp breaker for racked gear and 2 -15 amp breakers for lighting and non a/v plugs.

7.4.4 Atmos setup
Denon x4300
Sony str de597 - My first 5.1 reciever, now is being employed to run top rears
Behringer Inukes 6000 non dsp and 3000 non dsp for sub dutys
2 Dayton 18" 460HO-4 and 2 Dayton 18" Ultimax Subs all in DIY 4 cubic' boxes
Behringer FBQ 2496 for dsp
LCR Polk audio RTi A9
Surrounds and height are Volt 6s from DIY sound group - Erich is great, highly recommend!
Panasonic ae8000
Falcon AT Screen Scope 110"
Insteon switches controlling 7 zones
Logitech Harmony Elite remote

And my door... I love my door. 2 ply 3/4" Mdf with 3/4" Mdf trim and rivets with automatic door sweep and 5" wide throw hinges.

There are a few items left on the ole punchlist like grills for my riser, filling and painting a schwack of bullet holes and staining my stage and riser hardwood, but once you put that projector up things get hard.
Thanks for looking, Cheers.
